A Google Webmaster Help thread, written in Italian, has confirmed reports of a bug between Google's Blogger and Google Webmaster Tools.
Dennis G. from the Google Webmaster Team, who is specifically involved in the verification process, wrote in a Google Webmaster Help thread:"
It looks like we have a bug in our blogger integration. I'll go fix that. In the meanwhile, try verifying by meta tag instead.
It seems like he is the man that actually goes in to fix the "bug." How cool is that?
In any event, if you are having problems verifying your Blogger blog with Google Webmaster Tools, know that you are not alone.
There is no ETA for the fix, but Dennis made it sound like it is a quick fix.
